Listening to music from your ipod

Anyone using a portable speaker to listen to music from your ipod? I have came across the portable speaker from creative for ipod at http://creative.com/products/product...&product=15341 and was considering about getting one for my ipod. I prefer to listen from the speakers directly instead of through the earphones when I am at home but I do not want a big set of speaker system to take up my space as well. What do you think of the sound quality from the speakers? as i was also considering their xdock, I like the simplicity of the device
